Hello STM32 Community,I’m encountering an issue with the RTC on my STM32L4 microcontroller. When I connect VDD to the VBAT pin (without using a battery), the RTC is not functioning. However, if I use a battery for VBAT, the RTC works fine.Here’s the ...
Hello, I am a developer and I am using the L431RC chip on a custom board. I am using CAN BUS to communicate with the system, and during normal operation (via firmware), there are no communication issues,in fact, everything works quite well. However, ...
Hi folks, I am trying to interface Datai motor control unit for one of my projects using stm32f469I disc board. I am sending and recieving same CAN ID but unit is not giving data in live expression in stmcubeide. Can anyone tell me the solution of th...

Hi,I am using STM32G0B1CBT3 controller and would like to send and receive data in classic mode. I have configured all necessary parameters using cubemx but the buffer is getting full when I call this function HAL_FDCAN_AddMessageToTxFifoQ(&hfdcan1, &...
Hello, I am trying to vary the PWM frequency of Timer 2 in between 20Khz to 200 Khz in stm32G0C1RET6 Board.1. Whenever I change the Frequency from 200 Khz to 20 Khz, it works. but then I change it again to 200Khz it just doesn't work. my PWM line goe...
For the life of me I cannot get the I2C pins on my microcontroller to output anything.I am using I2C1 on pins PB6 (SCL) and PB9 (SDA) on the STM32F746VGT microcontroller. The pins are hooked up to a TXS0108E level shifter that has built-in pull up re...
Hello Everybody,MCU: STM32H750XB (STM32H750DK Discovery Kit)FDCAN Clock : 40MHzI'm experiencing an issue with my FDCAN bus configuration where the node enters Error state and issue persists with any data rate higher than the nominal rate of 500 kbps....
Hi folks, I need to use setup system where is 10BASE-T1S communication. And we have stm32H7 controller, so questions is which one would better use LAN8651 (MAC+PHY) chip and do controlling of chip via SPI or chose LAN8670 (PHY) and do chip controll...
I want to send data from my STM32 to another micro controller and I want to enable space parity, there is no setting to enable it, the only settings are none, odd and even. For space parity i want the parity bit to always be 0. I am using 9 bit UART...
